...bit x86. (This is documented in PR21510.) Specifically, GCC uses XMM0-XMM2 to pass the first 3 __m128 parameters, and the rest are passed on the stack. Clang passes an additional parameter by register, using XMM0-XMM3. The same applies to __m256 with YMM0-2 vs. YMM0-3. In theory, it would apply to __m512 as well, but currently clang doesn't support passing __m512 in x86 mode at all. ICC has the same behavior as GCC, and it seems that MSVC in 32-bit mode only *allows* up to 3 vector parameters per function (when not using __vectorcall), and these 3 are passed in XMM0-XMM2, which is closer to the...

...generate some SIMD code using LLVM. The SIMD code will be using INTEL MIC intrinsics and I'm not sure about the steps and tool set that I need to use to generate those. I also have a confusion on the following problems: 1. Do people usually generate SIMD code at source code level, using __m512? 2. If not, does LLVM have corresponding IR instructions for the SIMD registers and instructions? Since I'm new, I would appreciate any help that could give me some directions at any level. Some references would also help. Thanks in advance! -- Sincerely, Linchuan -------------- next...

...e with 3 __m256 elements Vectorcall Extension ---------------------------- Vectorcall extends the standard x64 calling convention while adding support for HVA and vector types. There are four main differences: - Floating-point types are considered vector types just like __m128, __m256 and __m512. The first 6 vector typed arguments are saved in physical registers XMM0/YMM0/ZMM0 until XMM5/YMM5/ZMM5. - After vector types and integer types are allocated, HVA types are allocated, in ascending order, to unused vector registers XMM0/YMM0/ZMM0 to XMM5/YMM5/ZMM5. - Just like...
